A CAUTION
• When removing the radiator cap, wait at least ten minutes
after the engine has stopped and cooled down. Otherwise,
hot water may gush out, scalding nearby people.
Radiator Water Leakage
1. Pour a specified amount of water into the radiator.
2. Set a radiator tester (Code No: 07909-31551). Increase water
pressure to the specified pressure.
3. Check each section for water leakage.
4. When water leakage is excessive, replace the radiator. If
water leakage is caused by a small pinhole, correct the
radiator with radiator cement.
No leak at 137 kPa
